    rxp x supercharger help

    I am interested in putting in a stock rxp x supercharger in my rxp. My question is, what other mods will I have to make? To the SC? Or PWC? Any help would be great! Thanks...

    you wont need to make any mods to the supercharger but you will need bigger fuel injectors so you dont run lean. you need 42lb fuel injectors

    Interesting how Dan says to run the stock 38's with the stock IC and everyone else says 42's are needed with the upgraded X-charger on the stock IC.

    I'm thinking of dropping a X-charger in my ski also. I wonder if the 14/19 4 blade will be too small?

    Don't forget the air intake side the 4" or rear air will be the reason more fuel is needed. I think Dan referd to the stock set up

    Depending on the temps the 14/19 should be right at 8100 RPMs. I switched to the X charger and put in 42s and now that the air and lake temps have come up to 70s and 80s I stick at 8100 with the occasional 8150. When it was colder it was hard to keep it off the limiter.

    Ok. In Dec when the air temp was 55 and water was 55 I was at 8100 rpm with an 82mm ring.
